When you left me, couldn't believe it
I thought that we had magic
I thought that we were special
But it's over, huh
Believe it, I can't fathom 
This terrible reaction to checking my phone 
Damn you're madder than a mad hatter

Quick can't believe it's over
Quick can't you come over

Shit I miss you darling 
Hee, I'm a one man lover
I'm not a Casanova
I can't believe it's over so quick
I, I called you, you didn't call me
I wanted you
You didn't return my messages
How could you be so, thick

Had a lot of women on you
Didn't like the fact that I wanted to own you
That's what you said to me
Said that "I wanted to lock you down" 
But you moved into my house
Gave me a son (mm, hmm, mm)

It was so quick the way that it happened 
Quick the way that you left me
Quick can't believe it's over
Can't believe it's over now

I loved you, I really loved you
Can't believe that it's over
Can't believe that we could ever split
I feel it in my stomach
I can't seem to move on
I'm sick from the knots that's happening
Medicines just ain't helpin'
I just can't seem to get well, and

Over, can't believe it's over
Over, can't believe it's over
Over, can't believe it's over
So quick

(Over) Can't believe it's over
(Over) Can't believe it's over
(Over) Can't believe it's over
So quick
